Square-body Fuses
PSC aR sizes 9x - 1500 VAC
Main characteristics
Ferraz Shawmut 1500 V PSC fuse-links provide maximum flexibility
in equipment design and ultimate protection for today’s power
conversion equipment. These square body fuse-links are availa-
ble in three different body sizes, each size having four world-
wide acceptable mounting styles. The different mounting styles
and body sizes along with a broad range of ampere ratings
allow greatest flexibility in equipment design.
The Ferraz Shawmut PSC fuses have been engineered to provide
state-of-the-art protection for SCR’s, diodes, thyristors, GTO’s and
IGBT devices. They have pure silver die-cut elements embedded in
solidified sand which helps control arcing characteristics for low
I
2
t and high breaking capacity. All contact surfaces are silver
plated and all hardware is non-magnetic.
All fuse links are equipped with a low voltage trip-indicator. This
trip-indicator can operate a field mountable microswitch which
is easily mounted directly on to the fuse even while in service.
